When the vehicle's engine is running, it spins the crankshaft, which is connected to the serpentine belt. As the crankshaft turns, it drives the belt, which, in turn, rotates the pulleys attached to the alternator and other accessories. The alternator contains a rotor that, when spun by the belt, generates electrical energy through electromagnetic induction. This energy is crucial for keeping the car battery charged and powering various electrical components, from headlights to infotainment systems.

A tensioner belt pulley is part of the vehicle's serpentine belt system, which drives multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. The tensioner itself is a spring-loaded or hydraulic device that maintains tension on the serpentine belt, ensuring it remains tight enough to function properly without slipping or breaking. The pulley, which is an integral part of this mechanism, assists in guiding the belt around the engine's various pulleys while providing the necessary tension.
